Every pay calculator on the internet assumes you work five eight-hour days. If you work a hitch, a rotation or three twelves, none of them can tell you your real number. These are worked examples with the actual arithmetic shown — where the overtime comes from, what the deductions take, and what lands in your account.
Both free, neither needs an account. One checks a shift premium; the other models the hitch around it — including where ShiftPayCal is the faster of the two.
Pay44 has 4.87 stars from 12,550+ ratings and 21+ calculators. We have none of that. What we have is 14/14, 21/7, day rates and what you keep after tax.
The overtime premium that makes a correct stub look $1,540 short, the six missing hours worth $315, and the FICA line nobody checks.
$600/day beats $35/hr by $17,033 a year — and the overtime a day-rate worker may still be owed is worth more than twice that gap.
Your differential has to be inside your overtime rate, not paid beside it. The gap is half your differential times your overtime hours — up to $5,720 a year.
Federally, identical. In California without a properly voted alternative workweek, four tens hide eight overtime hours a week — $6,240 a year.
The hours pay three times more money. The raise pays more per hour of your life — and it is worth 20% more if you already work overtime.
Identical $2,400 a week, $18,075 a year apart in take-home — and the IRS rule that decides whether you keep it or owe it back.
Both pay exactly $530 a day worked. After tax the shorter rotation keeps $17.83 a day more, and the extra days return 13% less than the ones you already work.
The whole state tax difference is $1,595 a year — about 55 cents an hour. Five times less than the states people actually mean.
$10,747 gross a month, $8,285 after tax in Texas — and why 44 of your 84 weekly hours are overtime worth more than your regular pay.
$7,020 gross a month, $5,674 after tax in Texas — and why 36 hours never reaches overtime, which makes a fourth shift worth $60 an hour instead of $45.
$101,920 a year, $80,531 after tax — and to earn that in 40 hours you would need $49.00 an hour.
Overtime is calculated per week under federal rules, not per hitch and not per pay period. That one detail is why a rotation pays nothing like an annual salary divided by twelve, and why two workers on the same rate can take home thousands of dollars apart. Days on, days off, hours per day, the overtime threshold and your state all move the final figure more than the rate does.
